2004-07-20Fix a serious code pessimization problem. If an inlined function has a singleChris Lattner

2004-07-20Ignore instructions that are in trivially dead functions. This allows usChris Lattner

2004-07-20Rewrite cast->cast elimination code completely based on the information weChris Lattner
actually care about. Someday when the cast instruction is gone, we can do better here, but this will do for now. This implements instcombine/cast.ll:test17/18 as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15018 91177308-0d34-0410-b5e6-96231b3b80d8

Speed up SCCP substantially by processing overdefined values quickly. This patch speeds up SCCP by about 30-40% on large testcases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14861 91177308-0d34-0410-b5e6-96231b3b80d8

2004-07-15Fix PR404: Loop simplify is really slow on 252.eonChris Lattner
This eliminates an N*N*logN algorithm from the loop simplify pass, replacing it with a much simpler and faster alternative. In a debug build, this reduces gccas time on eon from 85s to 42s. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14851 91177308-0d34-0410-b5e6-96231b3b80d8

malloc lowering. This means that lowerallocations doesn't need targetdata anymore. yaay. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14835 91177308-0d34-0410-b5e6-96231b3b80d8
2004-07-13Factor some code to handle "load (constantexpr cast foo)" just likeChris Lattner
"load (cast foo)". This allows us to compile C++ code like this: class Bclass { public: virtual int operator()() { return 666; } }; class Dclass: public Bclass { public: virtual int operator()() { return 667; } } ; int main(int argc, char** argv) { Dclass x; return x(); } Into this: int %main(int %argc, sbyte** %argv) { entry: call void %__main( ) ret int 667 } Instead of this: int %main(int %argc, sbyte** %argv) { entry: %x = alloca "struct.std::bad_typeid" ; <"struct.std::bad_typeid"*> [#uses=3] call void %__main( ) %tmp.1.i.i = getelementptr "struct.std::bad_typeid"* %x, uint 0, uint 0, uint 0 ; <int (...)***> [#uses=1] store int (...)** getelementptr ([3 x int (...)*]* %vtable for Bclass, int 0, long 2), int (...)*** %tmp.1.i.i %tmp.3.i = getelementptr "struct.std::bad_typeid"* %x, int 0, uint 0, uint 0 ; <int (...)***> [#uses=1] store int (...)** getelementptr ([3 x int (...)*]* %vtable for Dclass, int 0, long 2), int (...)*** %tmp.3.i %tmp.5 = load int ("struct.std::bad_typeid"*)** cast (int (...)** getelementptr ([3 x int (...)*]* %vtable for Dclass, int 0, long 2) to int ("struct.std::bad_typeid"*)**) ; <int ("struct.std::bad_typeid"*)*> [#uses=1] %tmp.6 = call int %tmp.5( "struct.std::bad_typeid"* %x ) ; <int> [#uses=1] ret int %tmp.6 ret int 0 } In order words, we now resolve the virtual function call. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14783 91177308-0d34-0410-b5e6-96231b3b80d8
